The main purpose of this legislation, known as the Lung Cancer Screening Expansion Act of 2025, is to ensure that adults aged 50 to 80 who are at increased risk for lung cancer receive annual screenings without any out-of-pocket costs. The goal is to improve early detection of lung cancer, which can lead to better treatment outcomes and potentially save lives. Key provisions of this law require all health insurers, including group health plans and federal health programs, to fully cover annual lung cancer screenings using low-dose computed tomography (LDCT) or similar technologies.
